Findinding Top k Elements and Heavy Hitters in Data Streams



Friday, 27 July 2012, 15:00 to 16:30


Finding top k items  and finding heavy hitters in data streams are two well studied problems in streaming algorithms. We shall discuss two deterministic streaming algorithms, one for each of these two problems.
